Paris,

France, a civil company of France Application November 15, 1945, Serial No. 628,929 In France December 22, 1944 Claims.

Boxes made of metal or plastics are used generally for packing various products such as cleanmg materials, polish, cosmetics, foods and the like which must be as perfectly fluid-tight as possible. e e v This invention has for its object the provision,

etween the box and its lid, of a fit sufficiently tight to secure a satisfactory fluid tightness, in combinatioh with an arrangement whereby the lid can be tilted easily about an axis at right angles to the axis of the box, whereby the box can be opened and closed as readily as if a considerably looser fit were provided.

It is to be understood, however, that this invention is by no way limited to such specific embodiments and that it is much more generally applicable to all devices or articles comprising a pair of elements adapted to fit into one another; such connection between the elements of the deviee or article has the advantage of affording a most reliable assemblage that can be separated easily without using any special tool.

Thus, a button can be designed that constitutes a new article of manufacture and embodies the invention. I e 1 Severalembodiments of arrangements according to this invention are illustrated by way of example in the drawing appended hereto.

Figure 1 is a sectional view or a closed box designed according to one form of thi's invent io'n.

Figure 2 is a bottom plan view of the box lid shown in Fig. 1.

Figure 3 is a cross-sectional view of a modification.

Figure 4 is a cross-sectional view of a button embodying the invention.

Figure 5 is a plan view of Fig. 4 with the lid removed.

Figures 6 and '7 are top and bottom plan views respectively of the lid.

Figure 8 is a view similar to Fig. 4 and shows the manipulation for separating the lid from the box.

The box shown in Figs. 1 and 2 comprises a cylindrical box 20 and a similarly cylindrical lid 22 engaging the box.

The diameter of the cylindrical lid 2 is slightly smaller than that of the box; and possesses a certain amount of elasticity, which is necessary for the obtainment of a frictional and comparatively tight fit on the box. Fluid-tightness is thus secured satisfactorily.

The box has a bulging bottom 20 and raised circular portion 2| terminating in a sealing edge 2la and formed to present an external surface flaring outwardly toward the edge Ma. The depending portion 23 of the lid is of internally cylindrical form to provide for fluid-tightnessin combination with the sealing edge 21a of the box. The lid is formed with three ribs 24 arranged as the three apices of an isosceles triangle; a pressure exerted on the side of the lid at a point 25 diametrically opposite one of ribs 24 will tilt said lid about the virtual axis passing through the two other ribs 24 and initiate its lifting. In particular, such a box can be made of pressed material. In replacing the lid in position on the box, the parts are first moved into the approximate angular position represented in the modified construction shown in Fig. 8. After the box is thus partly inserted in the lid, pressureis applied at the partly open side and the box 20 is fully inserted in the lid 22, the parts assum ing the position shown in Fig. 1. This mode of rf'mov'ing and applying the lid is rendered possible b'y thefla'ring shape of the box and the nar row line of firm contact between the sealingedge Na and the cylindrical internal surface or the depending lid portion 23 provides a fluid tight joint between the box parts.

In the embodiment shown in Fig. 3 the lid is received in the container 3! it is provided with three ribs 32 resting on the edge 33 of the container; in opening the same, as in the preceding case, a pressure is to be exerted on the side thereof at a point 34 diametrically opposite with one of the ribs 32, which results in tilting the lid about the virtual axis through the two other ribs 32.

The button shown in Figs. 5 to 8 is composed of two main parts that can be called the box 41 and the lid 42 by analogy with the corresponding elements of a box designed on the same principle and in order to retain the same designations as in the preceding.

The dropped edge 43 of the lid is of cylindrical form internally and adapted to fit over the sealing edge 44a at the large end of the flaring raised portion 44 of the box.

The lid 42 is formed, over a sector comprised between and A; of its whole circumference, with a shoulder 45 that is to rest on the sealing edge 44a of the raised portion 44 of the box 4|.

Provided in the middle of that zone at the underside of the dropped edge 43 where said shoulder is lacking is a tooth 46 designed to enable the user easily to locate the point at which he must press in the directions indicated by arrows F1 and. F2 for the purpose of tilting the lid about the extremities of shoulder 45 and thereby to lift the same at its opposite side in the direction shown by arrow Fa.

Obviously, the box might be provided with suitable holes through which the yarn intended to fix the button could be threaded; generally, however, holes so drilled in a pressed material part have very sharp edges. Such a practice would involve the risk of the yarn being cut and the button getting loose.

As a remedy for said inconvenience a large hole 41 is provided at the centre of the box through which the yarn can be threaded without the liability of rubbing against the edges thereof and consequently of being broken; said yarn 43, to be stitched through the fabric to which the button is to be fixed, is passed about a member 50 formed with a median core having frusto-conical extensions 52 projecting coaxially at either side thereof.

In order to retain said part 53 from rotating and consequently from undesirably twisting both the yarn bundles 48 and the fabric 49, ribs 53 are formed in the box 4! for retaining the extensions 52 on part 50 in their positions.

A button so designed has manifold advantages; thus, for instance, it has no visible fastening means since the yarn is hidden within the lid 42; moreover, one and the same box can be used with different lids variously decorated, coloured and shaped as suggested in Fig. 6, whereby the appearance of the garment to which they are secured can be changed most easily and at low cost.

In order to strengthen the lid 42 and so that same can be tilted more easily when it is to be detached from the box 4| by a pressure in the direction shown by the arrows F1 and F2, a projection 54 may advantageously be formed at the centre of the underside of lid 42, which is recessed to match the median core 5! and which comes into engagement therewith when the shoulder 45 bears on the raised upper edge 44 of box 4!.

It is to be understood that this embodiment of the invention is given merely as a non-limitary indication and that many modifications can be made therein without thereby departing from the scope of this invention.

What I claim as my invention and desire to secure by Letters Patent is:

1. In a fastening, a female element having a substantially cylindrical internal surface and a male element having an external surface of progressivel flaring form terminating at its relatively wide extremity in a sealing edge of greater external perimeter than the internal perimeter of the cylindrical surface whereby when the male element is fully inserted and compressed within the female element the relatively narrow line of close contact formed between the sealing edge and the internal cylindrical surface provides a fluid-tight joint between the two elements, the internal cylindrical form of the female element preventing the compressive force exerted by the male element from acting in an axial direction tending to relatively displace and separate said elements, and means forming a fulcrum about which one element may be tilted with respect to the other about an axis at right angles to the axis of said elements.

2. A fastening as claimed in claim 1 wherein the tilting axis is displaced from the axis of the elements.

3. A fastening as claimed in claim 1 wherein the tilting axis is disposed in the plane of the sealingedge.

4. A fastening as claimed in claim 1 wherein at least one of said elements is formed of pressed material.

5. A fastening as claimed in claim 1 in which one of the elements constitutes the body of a con-- tainer and in which the other of the elements constitutes the lid of the container.
